Transmit/Receive (Tx/Rx) Enable
Pin 27 (TX_EN) and pin 12 (RX_EN) are used to enable the
transmit and receive port, respectively.
Pin 28 (T_R) is used to control the Tx/Rx switch.
Tx/Rx Enable and Tx/Rx Switch Mode Control
The following control logic is used to configure the transmit or
receive mode of the SKY65336-11:
High Transmit mode
Low Receive mode
High Power and Low Power Modes
High power mode output is 20 dBm and low power mode output
is 10 dBm. Pin 26 (TX_HLB) sets the transmit path in high power
or low power mode according to the following logic:
High power mode
Low power mode
Bottom Center Paddles
The bottom center paddles must be electrically grounded for
proper RF performance. Customers should place adequate
thermal vias under the ground paddles for optimum thermal
performance. The Evaluation Board layout (see Figures 3 and 4)
can be used as a guide for RF ground and thermal layout.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
SKY65336-11 are provided in Table 2. Recommended operating
conditions are noted in Table 3 and electrical specifications are
provided in Table 4.
Typical performance characteristics of the SKY65336-11 are
shown in Figures 3 through 12.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. Instructions on the
shipping container label regarding exposure to moisture after the
container seal is broken must be followed. Otherwise, problems
related to moisture absorption may occur when the part is
subjected to high temperature during solder assembly.
The SKY65336-11 is rated to Moisture Sensitivity Level 3 (MSL3)
at 260 qC. It can be used for lead or lead-free soldering. For
